In this situation, the tool does not start even if turning the
tool off and on. To release the protection lock, remove the
battery, set it to the battery charger and wait until the
charging finishes.
Adjusting depth of cut
CAUTION:
• After adjusting the depth of cut, always tighten the lever
securely.
Loosen the lever on the side of the rear handle and move
the base up or down. At the desired depth of cut, secure
the base by tightening the lever. (Fig. 6)
For cleaner, safer cuts, set cut depth so that no more than
one blade tooth projects below workpiece. Using proper
cut depth helps to reduce potential for dangerous
KICKBACKS which can cause personal injury.

cutting line on the workpiece. (Fig. 7)
